A new USPTO patent filing has revived rumors that NFC-based Mac-to-iPhone syncing is in development. The patent for an "electronic device with conductive housing and near field antenna" would have a computer or any other display-equipped device carry spiral antennas to pick up near-field communications from a smartphone or other mobile device when brought close. Its example design, which resembles an iMac or a similar computer display, would work with multiple devices put typically within about four to eight inches away.
